The must show it is "serious" about tackling Islamophobia, said Labour Party Chair Anneliese Dodds after a series of fresh accusations over the Tories' failures to support British communities.
The Labour MP wrote to her Conservative peer at the start of Islamophobia Awareness Month calling on the government to do more to stamp out anti-Muslim hatred on the rise in the UK.
The former shadow chancellor said the Tories must establish a working definition for Islamophobia and implement it in full, according to the recommendations from the Singh Investigation.
That probe found evidence of "anti-Muslim sentiment" across the Conservative Party.
Anneliese Dodds wrote on Twitter: "The Conservatives are in denial about Islamophobia in their own ranks.
"Bizarrely, they can't even use the term Islamophobia."
The Conservatives rejected a formal definition of Islamophobia from the in 2019.
This definition, accepted by the Labour Party, states: "Islamophobia is rooted in racism and is a type of racism that targets expressions of Muslimness or perceived Muslimness."
Instead, the UK Tories said they would set up an inquiry to establish their own working definition.
Muhammad Asim, appointed to lead the inquiry, later claimed his communications with government officials were ignored. Asim was sacked in June after allegedly backing protests over the screening of a controversial film depicting the Prophet Muhammad's daughter.
Last week, reports emerged that the Tory party had quietly dropped efforts to establish a working definition for Islamophobia, with Communities Secretary Michael Gove actively against any official terminology.
Dodds said "denial" over the issue was not a "good enough" response.
°®Âþµº has sought confirmation from Dodds' office on whether the Tories replied to her letter, but has yet to receive a response.
